Lattice-Based Lightweight Quantum Resistant Scheme in 5G-Enabled Vehicular Networks

Both security and privacy are central issues need to be properly handled because communications shared among vehicles in open channel environments of 5G-enabled vehicular networks. Several researchers have proposed authentication schemes address these issues. Nevertheless, not only vulnerable quantum attacks but also use heavy operations generate verify signatures messages. Additionally, an expensive component RoadSide Unit (RSU)-aided scheme during the joining phase. To issues, we propose a lightweight quantum-resistant according lattice method Our proposal uses matrix multiplication instead operations-based bilinear pair cryptography or elliptic curve messages vehicles. satisfies significant reduction performance, which makes it enough handle attacks. is based on 5G technology without using any RSU-aided scheme. Security analysis showed that our properties as well resists Finally, shows favorable performance compared other related work.
